OSLO, Norway (UPDATED) – The bookies' odds point towards the Koreans, or Donald Trump. The experts are betting on the fight against sexual violence or defenders of the press. But all speculation ends Friday, October 5, when the Nobel Peace Prize is unveiled in Oslo.

At 0900 GMT, the annual Nobel prize-giving week reaches its peak as the 5-member Norwegian committee ends the guessing game by announcing this year's winner.

And anticipation is likely to be heightened after the postponement of this year's Literature Prize for the first time in 70 years over a rape scandal that came to light as part of the #MeToo movement which took off exactly a year ago.

This year, a total of 331 individuals and organizations were nominated for the prestigious peace award, almost a record number. But with the list a closely guarded secret, guessing who might be a contender is largely a game of chance.

Among the bookmakers, the choice was largely unanimous with North Korean leader Kim Jong Un and his South Korean counterpart Moon Jae-in frontrunners for the prize for their efforts at rapprochement between the two nations.

But choosing Kim may be a step too far for the Norwegian committee, given the UN's damning verdict on North Korea's "long-standing and ongoing systematic, widespread and gross violations of human rights".

Another unexpected favorite is Donald Trump, who at 7-1 is one of 3 frontrunners flagged by online bookies Betsson, with the odds suggesting the bombastic American president is 10 times more likely to win than figures like France's Emmanuel Macron or Russia's Vladimir Putin.

Taking a step back from the international spotlight, several Nobel experts see the prize honoring those involved in the fight against sexual violence at a time when the aftershocks of the #MeToo movement are still making waves around the globe.

A top contender would likely be Congolese gynecologist Denis Mukwege, better known as "Doctor Miracle", who has spent two decades helping women recover from the violence and trauma of rape in war-torn eastern Democratic Republic of Congo.

Another possible laureate is Nadia Murad, a 25-year-old Yazidi woman who was kidnapped by Islamic State militants in 2014 and endured 3 months as a sex slave before managing to escape.

Taking on 'fake news'

One area yet to be honored by the Nobel committee is the campaign to protect press freedom, which has been spearheaded by organizations like the Committee to Protect Journalists (CPJ) and Reporters Without Borders (RSF).

Such an award would be a nod to the role of a free press as a pillar of democracy at a time when the profession is increasingly under threat from repression, violence and the proliferation of "fake news".

Last year, the prize was won by the International Campaign to Abolish Nuclear Weapons (ICAN).

The 2018 Nobel season opened on Monday, October 1, with two immunologists, James Allison of the US and Tasuku Honjo of Japan, winning the Medicine Prize for research into how the body's natural defenses can fight cancer.

The Physics Prize on Tuesday, October 2, was won by 3 scientists, Arthur Ashkin of the United States, Gerard Mourou of France and Donna Strickland of Canada, for inventing optical lasers that paved the way for advanced precision instruments used in corrective eye surgery.

And on Wednesday, October 3, US scientists Frances Arnold and George Smith and British researcher Gregory Winter won the Chemistry Prize for applying the principles of evolution to develop proteins used to make everything from biofuels to medicine.

This year's award season will end on Monday, October 8, with the economics prize.

Up to 3 nominees can share the prize, which consists of a gold medal, a diploma and a cheque for 9 million Swedish kronor (around $1 million or 867,000 euros).

The award will be presented at a ceremony in Oslo on December 10, the anniversary of the 1896 death of prize creator Alfred Nobel, a Swedish philanthropist and scientist. – Rappler.com
